Features:
- distribution of incoming traffic across EC2 instances in a single Availability Zone or multiple Availability Zones.
- automatic request handling capacity scaling in response to incoming application traffic.
- when used in a Virtual Private Cloud (VPC), you can create and manage security groups
- when used in a VPC, you can create a load balancer without public IP addresses to serve as an internal (non-internet-facing) load balancer.
- can detect the health of EC2 instances. When it detects unhealthy load-balanced EC2 instances, it no longer routes traffic to those and spreads the load across the remaining healthy instances.
- Amazon Route 53 can be configured to perform DNS failover for your load balancer endpoints. If the load balancer or the application instances registered with ELB become unavailable, Route 53 will direct traffic to another ELB or destination.
- supports the ability to stick user sessions to specific EC2 instances.
- supports SSL termination at the Load Balancer, including offloading SSL decryption from application instances, centralized management of SSL certificates, and encryption to back-end instances with optional public key authentication.
- flexible cipher support allows to control the ciphers and protocols that are accepted by ELB in the SSL negotiation for client connections.
- supports use of both the Internet Protocol version 4 and 6 (IPv4 and IPv6).
- ELB metrics such as request count and request latency are reported by Amazon CloudWatch.
